New modulation-doped quantum semiconductor structures that exhibit strong Fano interference effects have been designed and demonstrated. Intersubband absorption experiments clearly demonstrate the ability to engineer Fano resonances and their evolution toward bound-to-bound transitions as the continuum is progressively modified under the action of an electric field normal to the layers.

  8. The phase of the wave function is fixed by the AlGaAs barrier on the right-hand side of Fig. 1, assumed to be infinitely thick.
  9. A small baseline correction (~λ3) is subtracted to take into account the free-carrier absorption of the electrons that are removed from the quantum wells and moved into the Al0.165Ga0.835As barrier by the field at U = −5 V.
  10. The spectra were calculated self-consistently in the envelope function approximation, incorporating the nonparabolicity by an approach described inC. Sirtori, F. Capasso, J. Faist, S. Scandolo, Phys. Rev. B 50, 8663 (1994). The discontinuity ΔEc = 0.298 eV for the aluminum content x = 33%, ΔEc = 0.145 eV for x = 16.5%, the nonparabolicity coefficient γ = 5.8 × 10−19 m2, and the effective mass m*/m0 = 0.067 + 0.057x were used.
